MACHINE FOR SHELLING PEAS.

SPECIFICATION forming part of Letters Patent No. 394,630, dated December 18, 1888.

Application filed June '7, 1886. Serial No. 204,421. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL \VILSON, a subject of the Queen of Great Britain, and a resident of the city of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Machine for Shelling Peas, of which the following is a specification.

My invention relates to machines for shelling peas.

My device consists of a hopper, similar to the feed-box of a straw-cutter, placed at an angle, which is fastened at or near its lower extremity to the frame of the rollers by a hinge or other proper device, so that the hopper will be movable and can be shaken by the eccentric wheels or cams hereinafter referred to. The rollers are incased inrubber and revolve in different directions, whereby the pod is broken and the peas expelled therefrom without crushing the pea. The movable hopper is shaken by means of eccentric wheels or cams revolving on the shaft below the bedplate, which shaft is operated by the cogwheel of a shaft running parallel with the hopper and operated by the cogs upon the driving-wheel. This will more fully appear by reference to the accompanying drawings, in which- Figure 1 is a side View or elevation of the machine. 2 is a sectional view of the machine, taken on the central line. Fig. 3 is a top view of the machine with a portion of the bed-plate removed, disclosing the shaft and the eccentric wheel or cam by which the hopper is shaken.

Like letters refer to corresponding parts.

A is the movable feeding hopper or frame, and B the bed plate or bottom, which maybe made of wood or metal, and the upper part of which may be in the form of a sieve, as shown at S, through which will pass any dirt which may be among the pods when placed in the machine. I prefer a bed-plate made of wood and corrugated or grooved, as shown in Fig. 3. This will greatly aid in keeping the pods straight and presenting them endwise to the rubber rollers.

The hopper A, at or near its lower extremity, is fastened to the frame supporting the rollers by hinges or hooks and eyes, or in any other proper manner, so as to allow the hopper to be shaken by the eccentric wheels or cams upon the shaft e, as hereinafter described.

0 are two rollers incased in rubber, and so adjusted by means of a thumb-screw that as they revolve in opposite directions they will grasp and pull between them the pod of the peas.

The driving-wheel D is hung upon the axle of one of the rubber rollers, which turns the other roller by means of the small cog-wheels a a.

The driving-wheel D is provided with cogs l), turning the shaft 0, which by means of engaging cogs h turns the shaft 6, upon which are hung one or more eccentric wheels or cams (Z (l, which as they revolve strike the under side of the bed-plate B, shaking the hopper rapidly.

1 y are rubber stops, upon which the hopper will fall after being raised and released by the eccentric wheel or cams.

z is the receiver into which the peas fall from the pods.

Should it be found in practice that the rollers C become coated with dirt or gum, they may be kept clean by scrapers properly adjusted against each roller, as shown at ff, Fig. 2.

The machine may be of small hand size and made to rest on the edge of the table, having guards i i, like the machine illustrated by drawings; or it maybe of larger size, resting upon legs and operated by power.

In operation the unshelled peas are placed in the hopper over the sieve S. The shaking motion given to the hopper by the eccentric wheels or cams (I (1 sends the pods along the longitudinal grooves in the bed-plate until they reach the rubber rollers C, which grasp them by the ends and pull between them the pods of the peas. The peas themselves, being forced backward, burst the pod and fall into the receiver ,e', while the shucks are drawn between the rollers and fall upon the other side.

Vhat I claim, and desire to secure by Letters Patent, is
